Hello!
Somewhere between 2.6.26 and 2.6.27 WOL stopped working on my MS-7350
motherboard with an "nVidia Corporation MCP51 Ethernet Controller (rev a3)".
"etherwake 00:19:db:f2:e1:35" did not work
"etherwake 35:e1:f2:db:19:00" did work
Since I did a BIOS update during the same time window I (wrongly) put
the fault on the BIOS. (See /sys/class/dmi/id/modalias for yourself:
dmi:bvnAmericanMegatrendsInc.:bvrV1.7:bd07/29/2008:svnMSI:pnMS-7350:pvr1.0:rvnMSI:rnMS-7350:rvr1.0:cvnToBeFilledByO.E.M.:ct3:cvrToBeFilledByO.E.M.:
)
Today I finally found the time to test various old versions of
"drivers/net/forcedeth.c" and also did a "git-bisect v2.6.26 v2.6.27"
which lead to the following culprit:

|
| When hibernating in 'shutdown' mode, after saving the image the suspend hook
| is not called again.
| However, if the device is in promiscous mode, wake-on-lan will not work.
| This adds a shutdown hook to setup wake-on-lan before the final shutdown.

my servers with nvidia ck804 and mcp55 will reverse mac address with kexec.
it turns out that we need to restore the mac addr in nv_shutdown().

Reverting that patch on top of drivers/net/forcedeth.c from 2.6.28.2
resolves the problem for me.
I DON'T use kexec, just simple poweroff.

can not find the reason why the WOL doesn't work...
please post
1. boot log for just after AC is pluged-in... ===> you should have
"nv_probe: set workaround bit for reversed mac addr"
2. and boot log after boot from WOL...==> you have have "nv_probe: set
workaround bit for reversed mac addr" too.

Impact: fix mac reverse for wol
some BIOS may already reverse that, try to don't touch the mac addr, so don't
confuse the WOL

Well, it doesn't look like it's going to, but testing is necessary.

Strage, at the moment I can't seem to reproduce the problem. I've
switched back to the version of 2.6.28.3 and now it seems to work.
I'll continue with tesing.
Some additional data:
The BIOS-upgrade tool (Afud408.exe) resets the MAC address. I had to run
the tool a second time to re-programm the MAC-address using its /M
option. I useed the unreversed MAC-address back than.
I also tried the reversed address once, but after that forcedeth.c
complained about a wrong MAC-address.
If I completely turn off the power (pull the plug), WOL doesn't work,
even when it's enabled in the BIOS.
Only after I'v started Linux, do "echo NMAC > /proc/acpi/wakeup" and
"ethtool -s eth0 wol g" does it work again.
Nether the less here's the output of dmesg:
forcedeth: Reverse Engineered nFoce ethernet driver. Version 0.61.
ACPI: PCI Interrupt Link [LMAC] enables at IRQ 23
forcedeth: 0000:00:14.0: PCI INT A -> Link[LMAC] -> GSI 23 (level, low) -> IRQ 23

The line maked * was inserted by me in the source file for my debugging.

Hmm, I had not tried WOL for some time.
With 2.6.29-rc3 is see the following behaviour:
State WOL Behaviour
------------------------------
shutdown reversed MAC
disk/shutdown reversed MAC
disk/platform OK
Apparently nv_restore_mac_addr() restores the MAC in the wrong order
for WOL (at least for my PCI_DEVICE_ID_NVIDIA_NVENET_15). platform
works, because the MAC is not touched in the nv_suspend() path.
A possible fix might be to only call nv_restore_mac_addr() if
system_state != SYSTEM_POWER_OFF.

Your patch seems to work for my system, too. (Expect for the case where
I do "poweroff" from busybox or do Alt-SysRq-O; Debians version works,
as long as I remove the '-i' option:
-i Shut down all network interfaces just before halt or reboot.

Patches against ext3 have been posted by Jan Kara and have been sucked
into the mm tree. I don't know if Andrew is planning on waiting until
the next merge window, or is planning on pushing it sooner given that
it is a regression. (These supercede the ones currently posted by
Eric in the BZ entry.)
Similar patches have been posted against ext4, and I will be handling
them in the ext4 tree.

Yes, I have jbd-fix-return-value-of-journal_start_commit.patch and
revert-ext3-wait-on-all-pending-commits-in-ext3_sync_fs.patch queued
for 2.6.29.
The secret algorithm for determining this is to peek in the series file
(http://userweb.kernel.org/~akpm/mmotm/series) and see where I positioned the
patch:

As I said earlier I have received a patch that I applied locally and
that fixes the problem.
As to if and when the patch actually appears in the kernel is out of
my control, and nobody told me that it was applied.
If you believe it was applied to a kernel version that is readily
available for download I am wiling to test such version.
Thanks

I never received the email referring to a particular commit because
I am not subscribed to LKML. The commit revert seemed to work OK on
gameport.c, but I get an error that gameport.h requires merge
resolution.
Can you send the gameport.c and gameport.h files to me with the
reverted commit, or tell me how to get this resolved?
Please CC me directly.
Thanks,
Andy Johnson

Please try the patch below. It's not a simple revert of 6902c0be, needed
some manual tweaking.

There is a fix against scsi-misc:
http://marc.info/?l=linux-scsi&m=123371501613019&w=2
I might need to fix it in a different way though.
There are other pending patches to fix other sg oops in scsi-misc so
the above fix can't be cleanly applied to 2.6.28.X. I'll send a patch
for 2.6.28.X once I get SCSI maintainer's ACK on it.
Sorry for the inconvenience,

I've looked at the traces but lack the skill to make any sense out of them.

A general question: what's going on? I guess this will only be answered
by me getting my hands dirty and understanding how ftrace works and how
the output maps to what's happening. I'll look at the docs for a while.
A specific question for now is how can I identify long latency within
qemu here? As far as I can tell all qemu latencies in trace6.txt are
sub 100ms, which, while long, don't explain the guest stalling for many
seconds.

Exactly - that in turn means that there's no scheduler latency
on the host/native kernel side - in turn it must be a KVM
related latency. (If there was any host side scheduler wakeup or
other type of latency we'd see it in the trace.)
The most useful trace would be a specific set of trace_printk()
calls (available on the latest tracing tree), coupled with a
hyper_trace_printk() which injects a trace entry from the guest
side into the host kernel trace buffer. (== that would mean a
hypercall that does a trace_printk().)

Does the bug reproduce if you use the acpi_pm clocksource in the guests?

In the guest being pinged? Yes, it still happens.
hermes-old:~# cat /sys/devices/system/clocksource/clocksource0/available_clocksource
kvm-clock acpi_pm jiffies tsc
hermes-old:~# cat /sys/devices/system/clocksource/clocksource0/current_clocksource
acpi_pm
kmshanah@flexo:~$ ping -c 600 hermes-old
--- hermes-old.wumi.org.au ping statistics ---
600 packets transmitted, 600 received, 0% packet loss, time 599439ms
rtt min/avg/max/mdev = 0.131/723.197/9941.884/1569.918 ms, pipe 10
I had to reconfigure the guest kernel to make that clocksource
available. The way I had the guest kernel configured before, it only had
tsc and jiffies clocksources available. Unstable TSC was detected, so it
has been using jiffies until now.
Here's another test, using kvm-clock as the guest's clocksource:
hermes-old:~# cat /sys/devices/system/clocksource/clocksource0/current_clocksource
kvm-clock
kmshanah@flexo:~$ ping -c 600 hermes-old
--- hermes-old.wumi.org.au ping statistics ---
600 packets transmitted, 600 received, 0% packet loss, time 599295ms
rtt min/avg/max/mdev = 0.131/1116.170/30840.411/4171.905 ms, pipe 31

Hi Kevin,
I've looked a bit at your traces.
I think it's probably too wide to find something inside.
Latest -tip is provided with a new set of events tracing, meaning
that you will be able to produce function graph traces with various
sched events included.
Another thing, is it possible to reproduce it with only one ping?
Or testing perioding pings and keep only one that raised a relevant
threshold of latency? I think we could do a script that can do that.
It would make the trace much clearer.
Just wait a bit, I'm looking at which event could be relevant to enable
and I come back to you with a set of commands to test.

Yeah, I think that should be possible. If you can come up with such a
script, that would be great.

Excellent! Thanks for looking into this.

Ok, I've made a small script based on yours which could do this job.
You will just have to set yourself a threshold of latency
that you consider as buggy. I don't remember the latency you observed.
About 5 secs right?
It's the "thres" variable in the script.
The resulting trace should be a mixup of the function graph traces
and scheduler events which look like this:
gnome-screensav-4691 [000] 6716.774277: 4691:120:S ==> [000] 0:140:R <idle>
xfce4-terminal-4723 [001] 6716.774303: 4723:120:R + [001] 4289:120:S Xorg
xfce4-terminal-4723 [001] 6716.774417: 4723:120:S ==> [001] 4289:120:R Xorg
Xorg-4289 [001] 6716.774427: 4289:120:S ==> [001] 0:140:R <idle>
+ is a wakeup and ==> is a context switch.
The script will loop trying some pings and will only keep the trace that matches
the latency threshold you defined.
Tell if the following script work for you.
You will need to pull the latest -tip tree and enable the following:
CONFIG_FUNCTION_TRACER=y
CONFIG_FUNCTION_GRAPH_TRACER=y
CONFIG_DYNAMIC_FTRACE=y
CONFIG_SCHED_TRACER=y
CONFIG_CONTEXT_SWITCH_TRACER=y
CONFIG_EVENT_TRACER=y
Thanks!
Ah and you will need python too (since bash can't do floating point
operation, it uses python here).

Yes, this looks like it will work as intended.
One thing I was thinking about though - would we need to look for a
trace that consists of a fast ping followed by a slow ping? If we only
keep the trace data from when we experience the slow ping, the guest
will have already "stalled" before the trace started, so the trace won't
indicate any of the information about how we got into that state. Is
that information going to be important, or is it enough to just see what
it does to get out of the stalled state?
Either way, I'll try to get some results in my maintenance window
tonight.
Cheers,
Kevin.

Yes, this looks like it will work as intended.
One thing I was thinking about though - would we need to look for a
trace that consists of a fast ping followed by a slow ping? If we only
keep the trace data from when we experience the slow ping, the guest
will have already "stalled" before the trace started, so the trace won't
indicate any of the information about how we got into that state. Is
that information going to be important, or is it enough to just see what
it does to get out of the stalled state?
Either way, I'll try to get some results in my maintenance window
tonight.
Cheers,
Kevin.

I don't know :-)
I fear the only thing we would see by looking at a fast ping trace
is the kvm going to sleep at the end. I guess the hot black box
here is likely: what happens when we try to wake up kvm and why it is
taking so long.
May be by looking at a slow ping trace, we could follow the flow once
the kvm is supposed to be awaken. At this stage, we can perhaps
follow both the scheduler and kvm activities. Hopefully after that
we can reduce more the trace, by filtering some specific areas.
It will likely end up with some ftrace_printk() (putting specific
trace messages in defined locations)...

Testing did not go so well. I compiled and booted
2.6.29-rc8-tip-02630-g93c4989, but had some problems with the system
load when I tried to start tracing - it shot up to around 16-20 or so. I
started shutting down VMs to try and get it under control, but before I
got back to tracing again the machine disappeared off the network -
unresponsive to ping.
When I got in this morning, there was nothing on the console, nothing in
the logs to show what went wrong. I will try again, but my next chance
will probably be Saturday. Stay tuned.
Regards,
Kevin.

I provided some more traces using Ingo's "tip" branch, but I don't think
anyone has looked at them yet.
http://bugzilla.kernel.org/show_bug.cgi?id=12465#c11
I can provide more traces if e.g. a different set of functions is
required, but I'm not going to be able to analyse them properly myself.
I should have a bit more time for testing next week and I plan to try
setting up the guest with the different virtual network adapters models
to see if that helps.
Cheers,
Kevin.

I provided some more traces using Ingo's "tip" branch, but I don't think
anyone has looked at them yet.
http://bugzilla.kernel.org/show_bug.cgi?id=12465#c11
I can provide more traces if e.g. a different set of functions is
required, but I'm not going to be able to analyse them properly myself.
I should have a bit more time for testing next week and I plan to try
setting up the guest with the different virtual network adapters models
to see if that helps.
Cheers,
Kevin.
